Ever since I updated to firefox 70, all of my desktop devices (windows, macos, and linux) firefox will ignore my theme and display look like the image attached. The top bar will be correct for my theme for a small moment and then it will turn white along with the firefox start search thing, the search thing will go back to dark but the top bar will stay white. This happens with any theme installed and with all themes uninstalled on every device. The only way to fix this is to go and enable some other theme and switch back to the theme I want.

I know it shows me using nightly, I installed it today to try fixing the issue but it doesnt. This happens in the standard version of firefox (72.0.1 current) and has happened on every update since v70.
